Extending the life of silicone diaphragm

Hello,
I need to extend the life of a silicone-nomex wastegate actuator diaphragm.
It is subjected to high temperature and it eventualy fails. Would coating it

with silicone oil result in longer life span until I find the replacement?
Can I do anything else to extend its life? This is for an automotive
application where the wastegate bypasses the exhaust gases around the
turbocharger in order to regulate the boost.
Regards,

You can try laminating the diaphragm with a very thin layer of brass
mesh coating with a fluorosilicone resin or epoxy resin. Check up if
the slight increase in thickness wil not matters.
